@marmot this looks right, and I think my main problem was that I had the wrong concept for the directions. The tree doesn't grow first right from the title and then down, but first down and then right. Thanks.

Why New York's Subway Still Uses OS/2
Every day 5.7 million people ride the subway in New York City -- and are subjected to both "the whims of the Metropolitan Transit Authority and the unheard-of reliability of a marginally successful operating system from the early 1990s." martiniturbide shared this report from Tedium: OS/2 and MTA consultant Neil Waldhauer said in an email, "For a few years, you could bet your career on OS/2." To understand why, you need to understand the timing. Waldhauer continues, "The design is from a time before either Linux or Windows was around. OS/2 would have s…

@JosephWright Let me try to explain better. While writing an answer to a question, I wanted to mention a user in the correct way (with @ in front, I assume). But since that user was not mentioned before in the question, I got no suggestions (as I do here in chat). Looking at the shown name of the user from answers, I see "Name Surname", and I suppose I cannot write @Name Surname. But how do I find out what to write. For Joseph Wright it would be @JosephWright, apparently.

@mickep normally the shown name simply works (in comments etc). But to be sure you can search some question or answer of the user, start a comment and start to type @..., then you will get a suggestion that you can copy and paste.

@UlrikeFischer @mickep @<some user> only pings that user if used in a comment AND if that user has already participated in the current thread. Copying and pasting from another thread doesn't make much sense.

@mickep not sure if they are still in operation, but there used to a few years back (2013 maybe?) on at least one route. Maybe it was Windows 3.1. I had a train enthusiastic Academic Councillor at the institute I wrote my Bachelor's thesis at who was part of the energy commission of Bayern, who told me.

> There's a radio station in New Orleans for the visually impaired. Every day, volunteers read the local newspaper, as well as best-selling books, mysteries, young adult novels, and stories for kids over the air.

@UlrikeFischer At the moment I've not set up to allow that 'officially', mainly because of the need to deal with backend code but also because with a patch-based approach \input{l3debug.def}\input{l3debug.def} will apply everything twice ...

I am trying to introduce LaTeX at work. To do that, I want to make a document with exercises of a programming language using Overleaf to share with my coworker. This PL has a file extension where I can use to paste the solution (code), using listings

However, this file is not enough to compile the program (it needs more stuff, such as the design window etc.). But in LaTeX is enough to use that file. So, what do you recommend?

Paste all code in one .tex file in Overleaf (will have a bunch of lines), or use the file extensions and attaching it into Overleaf (less lines of codes, with the problem that if the code is wrong/incomplete we will need to replace that file by a new one)?

I want to make a lot of exercises, so there would be a lot of attached files

Also, I am thinking of dividing the main .tex into sub .tex files. For example, if my document has 20 exercises then I will have 21 tex files, 1 for the title and the rest of exercises. The opposite of this is that I do not know how to do it, I have always worked with only one file

@manooooh For example, its file model is that you can have only one file per "project" that is a \documentclass{...} file; all others must be \include or \input. To me this makes it quite awkward to use.

@AlanMunn what do you mean? Overleaf has a max size of proyects so if I need more I cannot continue? (I don't care if Overleaf don't have the last updates of packages, I want to have a collaborative environment)

@AlanMunn if you had to work in a proyect in LaTeX with other people, what would you use, GitHub?

@manooooh Overleaf can deal with included files with no problem, but keeping them updated in the free version is a pain. I would do it with the paid version, but that's $15/month for up to 10 collaborators per project. This gives you integration with Dropbox and GitHub.

@manooooh No, by large projects I mean something that consists of a set of related but independent documents (as opposed to a single document with lots of includes).

@AlanMunn ok, thanks. So under this conditions would you separate every exercise into a new .tex file and then attaching into a main .tex file (every tex file would have the listings code directly, not attached to it)?

@DavidCarlisle that is a problem for me, unfortunately. At work I don't have people that use (La)TeX, so the best option for me (at least for now) is to have LaTeX in a simple way. Overleaf can do it, since we can use LaTeX (obsolete or not) without installing it, so that is good for me

@manooooh I'm not sure I understand. But if you had 20 exercises, but they would all be part of one document, then yes, it would make sense to have a single main.tex and then use \input to include them into the document. For the code I would also probably use listings version of \input.

I am the psychotherapist. Please, describe your problems. Each time
you are finished talking, type RET twice.
should manooooh use emacs
Emacs? Hah! I would appreciate it if you would continue.
Is it any good with tex files?
What do you think?
I think yes
What makes you believe you think yes?

@manooooh To return to Overleaf. I'm not suggesting that you don't use it. It definitely has its advantages for collaboration, and its rich text mode might be useful for non-LaTeX users too. But the free version's abilities for larger complex projects are more limited.

@AlanMunn around autumn/winter last year. The migration to v2 started earlier, but I think that was the time most of the systems were migrated. v1 was shut down 8th January this year, if I recall correctly.

@Skillmon Ok. So my information is outdated. So for example, suppose I had set of course lectures. Could I set up a single project in Overleaf where each week's lecture would be an independent beamer file?

@AlanMunn yes, this would be possible, though the handling of the different files might be unhandy. The \jobname will always be output because of the way the building system works, so you'd have to either provide a dedicated latexmkrc or download the generated PDFs for each \documentclass containing file individually. But I'm not too familiar with that feature as it is seldom used (and wasn't ever actively by myself).

@Skillmon Ok, so my info is not so wrong, in fact. To me this is a conceptual problem with Overleaf that makes it difficult to use for more complex projects rather than single documents. Of course everything is a tradeoff, and the collaborative tools of Overleaf are very helpful.

@DavidCarlisle I have a local installation. Sometimes I'm too lazy in creating a new local Proyect because I want to test something, so I create a Proyect on Overleaf to test. Then my final document is compiled on my local installation

Sometimes if the test is easily reproducible I use the integrated MathJax section of math.SE site, which is fast to achieve :P

Also, each Proyect that I start in Overleaf or locally I save it in both places. It's a matter of security, because if my machine dies I will have the latest version available online
